Just a heads up. Yesterday, for the umpteenth time, a Funeral Director sent me a draft order of service which included 'Ave Maria' played by the organist as a recessional. I asked the FD to check whether the family actually wanted 'As I kneel before you'. Sure enough they did. It's always worth clarifying to avoid upsetting the family.

Then theres the bride who wanted "that song from Robin Hood" expecting the schmaltzy Bryan Adams "Everything I do...." and instead got the silly bit of the Rossini overture that was used for the old B&W TV series.
I'm not altogether convinced it was a mistake.

The link in the second version of your post brought back a few memories, as I had that song on a 78 rpm record when I was about 8. I don't think it's by Rossini though, maybe you're thinking of the "Lone Ranger", though the Rossini extract was also used (with words) as the signature tune for a TV series about William Tell, which was pretty similar to one about Robin Hood also shown in the late 50s/early 60s.

Returning to the topic, I was asked to sing at a cousin's wedding several years ago: he wanted me to sing the Ave Maria, and when I asked which one he said "Oh, is there more than one?" When I sang a few bars of the Gounod setting he said "That's the one", so I asked about accompaniment, and he thought I could do it unaccompanied! I pointed out that the whole point of that piece is that it sits above a Bach prelude, so eventually he bought a second-hand electronic keyboard (it was a civil wedding in a Dutch stately home licensed for such things, so no organ available), got a friend to play it and then sold it afterwards. The volume wasn't particularly loud, so I had to watch the player's left hand to keep in time, a pretty fraught experience!
